Electronic Components Philippines: Resistors, Diodes, LEDs, ICs & Buzzers | Circuitrocks
Electronic Components at Circuitrocks — Your Bench Essentials
Fill your parts drawers with the basics. Our Components collection covers
resistors, capacitors, diodes, LEDs,
timers/ICs, and buzzers that you’ll use in almost every Arduino,
ESP32/ESP8266, or Raspberry Pi project.
These are the go-to parts for LED current limiting, pull-ups, protection, timing,
and simple alarms—perfect for starter kits, labs, and thesis builds.

FAQ
I’m new. Which components should I buy first?
Start with 220 Ω and 10 kΩ resistor packs, a set of 5 mm LEDs, a pack of 1N4001 diodes, one 555 timer IC, and an active buzzer. That combo already lets you build blinkers, buzzers, and basic protection circuits.
Are these parts safe to use with Arduino/ESP32/Raspberry Pi?
Yes—these are low-voltage, low-power components meant for 3.3–5V logic circuits. Always double-check wiring and use current-limiting resistors for LEDs and buzzers.
Do you have tutorials that use these SKUs?
Many of these parts appear in guides on learn.circuit.rocks and the Circuitrocks blog—perfect for class demos and student projects.
Do you ship components nationwide?
Yes—fast shipping anywhere in the Philippines, with same-day processing for in-stock orders before cutoff.
